Use the lvts_for_each_valid_sensor() helper in lvts_update_irq_mask() to ignore invalid sensors. Currently, since the invalid sensors will always contain zeroed out thresholds (from kzalloc), they will always get their interrupts disabled on this loop. So this commit doesn't change the resulting interrupts configuration, but it slightly optimizes the loop by skipping the invalid sensors, avoids potential future surprises if at some point memory is no longer allocated for invalid sensors, as well as makes the code more obvious.
